The ls command shows that the backup was creating a tar file successfully:

When only the backup image of the VIOS is required and not a file with NIM
resources, the -mksysb flag is used. With this flag, a file name is required with
the directory for the backup, for example:
$ backupios -file /home/padmin/backup_loc/VIOS.img -mksysb
For backups using the -file flag, backing up to an NFS mounted file system is
useful for saving the backup image on another machine.
Backup to NIM
You can use NIM to restore the Virtual I/O Server. The following procedure can
be used for creating the NIM resources (See Example 5-6 on page 284 and
Example 5-7 on page 284):
1. Export a NIM directory for mounting on the Virtual I/O Server.
2. Create the mksysb image on the NIM server by using NFS when running the
backupios command on the Virtual I/O Server. Use the -mksysb flag to create
the mksysb image only.
3. Create the NIM client if it is not already defined.
4. Create a SPOT resource from the mksysb image unless you already have a
SPOT at the correct matching level.
5. You are now ready to do a NIM install of the Virtual I/O Server.
